Are there any knowledgeable painters out there who can tell me the
best method to paint over a water-stained wall? A couple years ago,
the prior owner told me he had put several coats of white acrylic
latex paint over the area... but the water-stain eventually "bled"
thru. (This white acrylic latex paint is also the *original* paint for
all the drywall throughout my home... so if I must switch to an
oil-based paint to cover the water-stain, will it "stand out" from the
latex wallpaint?) Lastly, at the top portion of the water-stain,
there's some mold/mildew on the drywall… Should I first remove this w/
a diluted chlorine bleach solution before re-painting? (FWIW: The
water-stain ranges from 1 to 2 inches wide; and ~3 feet long.)

Thanx in advance for any helpful advice!

I've painted successfully and covered water stains and grease stains. The
thing I used was KILZ and it must be applied to the entire wall, not just
the spots, or you will see a difference in finish, as the rest of the wall
not covered will be more porous. I know you will HAVE to do something
about the mildew, but I have no experience on that one.

the only way to do it is with a sealer/primer, its Kiltz or something
like that, it comes in water based or oil based.. it will seal the paint
stain and not bleed though, just remember that when you finished with
the primer/sealer you got to paint over it.. when i used it in a laundry
room it looked too good to paint over....but we painted over it anyway..

oh and no, you don't need oil paint. Oil still wouldn't cover it. It's
the kilz that does the hiding and you can use latex or if you have paint you
used previously, you can use it. I've had a wall I treated with kilz and
painted that whole wall, but the other 3 walls in the room didn't need
treatment, and if you paint from corner to corner, you really can't tell
they have been treated differently because the light falls differently all
over the room. But you would be able to tell on the same wall. Well,
truthfull I did cheat somewhere. There was drippy stains under the
windows and I sealed with KILZ just on the wall right under the window
because the drapes would hang there and therefor break the line of vision
for comparison, so no problem.

I would clean the mildew with bleach and water.

The best stain sealer to use is Bin made by Zinsser. It is a
pigmented shellac and will cover water stains much better than Kilz.
In fact, if you use a water based Kilz, the stain will bleed through
in a matter of time.

Once you cover with Bin, apply a latex paint, not alkyd--mildew grows
much better on alkyd paints.

Before you do any of the above you should determine why there was
mildew in the first place and cure the problem.

Good luck,

Yes, you want to kill out and clean up the mildew with bleach before any
painting. This is one area where careful indoor prep is essential.

Then you need to paint with a stain sealer. There are several that will
serve. Shellac is the oldest, and still on the market. You thin it with
alcohol. Any good paint store will sell you a commercial sealer paint.
Two national brand names are Kilz and Z-Prime, but I have used Sherwin
Williams house brand sealer-primer to good effect. I forget what they
call it.

If you use Z-Prime, you will need to use a respirator, but the wall will
be dry and ready for the next coat in about 10 minutes.

Kilz. However - mildew/mold requires water to grow. You MUST FIX THE LEAK
or condensation before you try to paint the wall. You could have a really
serious problem behind the drywall. If you think paint is expensive, see
what replacing joists, rafters and a roof will cost you...
